It is not possible to display all available CAD marks at once as in traditional CAD prompting devices.
This illustrated the impossibility of "leading from behind" and prompted device makers to specialize rather than participate in a commodity hardware melee.
McCrea envisions a time when you will be able to hop into your car, turn on your navigation device, say a friend's name, prompting the device to pull up data from your cloud address book and guide you to their location.
"In the future, you'll be able to point your device at anything around you and, without prompting, that device will recognize what is there, incorporate your interests, and layer on information about what you're looking at," said Brian Blau, research director at Gartner Inc.

Furthermore, the circuit of the on-board voice prompt device is illustrated.
When someone is smoking, the prompt device can achieve automatic monitoring of cigarette smoke and send voice prompt signal.
This paper used active infrared detection technology to design a simple and reliable car voice prompt device with high sensitivity, in which infrared transceiver pipes are used for the monitoring of smoke content in the air inside the automotive environment.
Success rates were low with several devices, but were high using the audio-prompt device Auvi-Q.
However, success rates dropped after switching between a one-cap and a two-cap device without training and increased after switching to the audio-prompt device Auvi-Q.
